Tall rooms and open plans
If your home has a two-story foyer or family room, dust collects where nobody looks. Think of the tops of tall windows, the ledge above the front door, ceiling fan blades and the upstairs railing. Light from big windows shows every streak on an open kitchen's counters and appliances. A regular visit covers what you see and touch every day. Twice a year, book a deep clean for the high spots that can be reached safely and the build-up behind and under furniture. Open plans also carry dust and cooking smells from the kitchen into the living area, so steady, regular visits keep the whole space even. If your lower level is finished, count it in your rooms, with its bathroom, bar or playroom, so your hours match the house you really have.
